| Abstract: | Abstract In the chemical investigation on the saponin composition of leaves and stems of Panax quinquefolium L., two new minor dammarane saponins, quinquenoside L1 (1) and L2 (2) have been isolated. By means of physico-chemical evidences and spectral analysis their structures were established as 3-O-β-D-glucopyranosyl-(1-2)-β-D-glucopyranosyl]-20-O-β-D-glucopyranosy-dammara-23,25-diene-3β, 12β, 20(S)-triol (1) and 3-O-β-D-glucopyranosyl-(1-2)-β-D-glucopyranosyl]-20-O-β-D-D-glucopyranosyl-(24Z)-dammar-24-ene-3β, 12β, 20(S), 26-tetraol (2). |
